2 Claims. (Cl. 21556) indicated above in which the contents make nometallic contacts which would contaminate the same.

- Other objects and advantages of my invention will be apparent from areading of the following description in connection with the drawings,wherein for purposes of illustration I have .shown a preferredembodiment of my invention. 20 In the drawings:

Figure 1 is a transverse vertical sectional view through the embodiment.

Figure 2 is a plan view of the bottom of the outer cover.

15 Figure 3 is a bottom plan view of the inner Y cover.

Figure 4 is a side elevational view of the upper part of the containershowing the outer cover in place.

Figure 5 is a plan view of the compressible valve.

Referring in detail to the drawings, the numeral 5 refers generally to aglass or other similar transparent material cylindrical con- 5 tainerwhich has the outset upper portion which is thickened as indicated andprovided with the exterior screw threads 1 below its upper edge and thereduced upper portion 8 defining the radially outwardly arrangedshoulder 9 above 40 the screw threads I.

[The inner cover generally designated l comprises the plain metal diskll having the cen-- tral hole l2 therein and provided at its peripherywith the inverted U-shaped flange I: which forms a channel ll receivingthe reduced upper portion 8 on the upper end of the transparent ortranslucent receptacle 5. As shown in Figure 1 the channel ll closelyreceives the annular portion 8 and the disk portion ll of the innercover 50 is at a level below'the upper end of the portion 8 when theinner cover is in place.

The outer cover generally designated l comprisesthe metallic diskportion Ii which has the thickened depending annular portion 11 at its55 radially outward edge which terminates in the depending flange l8which has the plane portion I! for closely engaging the radially outwardside of the inverted U-shaped flange l3 0n the inner cover, and belowthis flange portion the internal threads 20 are arranged to engage withthe 5 threads 1 on the receptacle 5, whereby the outer cover is clampedto the receptacle 5 and the inner cover is clamped to the receptacle 5,and the inner and outer covers clamped to each other in a manner topositively seal the container and 0 positively prevent the passage ofair into the container from the outside thereof or from the containeroutwardly,

Around the middle of the disk It of the outer cover arecircumferentially spaced arcuate lugs 15 2| which areformed preferablyby pressing them into the disk It so that they depend from the undersideof the outer cover sufficiently to engage the top of the inner cover andproperly space the outer cover from the inner cover when the covers arein place.

The lugs 2| form the chamber in which is located the segmental crosssection circular compressible valve 22 which is arranged over the holel2 in the inner cover. The valve 22 is of at appropriate diameter andthickness so that when the outer cover and the inner cover are in place,the valve will be sufllciently compressed over the hole l2 in the innercover that entrance of air will be positively prevented, and asufliciently high vacuum may be retained within the receptacle topreserve the contents of the receptacle, such as green cheese and thelike substances which are readily perishable when, contacted with air.,i r

The outer cover is provided with; a pair of gas escape holes 23, 24which permit escape of gas from the receptacle which wasgenerated by thegreen cheese or the like within the receptacle and due to its pressurecauses a movement of the 40 valve 22 away from the opening l2,sufiicient to pass the gas into the space between the covers. The shapeand arrangement of'the valve 22 is such to permit this escape of gasunder pressure generated within the receptacle, but positively preventsthe entrance of air which may find its way into the space between thecovers through the holes-23, 24, therebypermittlng proper development ofthe cheese or the like while positively preventing air contaminationthereof. Because of the fact that no metal touches the cheese or thelike in the glass. or similar material receptacle, the covers beingspaced above the top of the cheese or the like, the cheese will also beprevented from being contaminated, such as, 86

for instance, takes place in instances where the cheese is packed incontact with tin receptacles.

Although I have shown and described herein a preferred embodiment of myinvention, it is to be definitely understood that I do not desire to"limit the application of the invention thereto,

and any change or changes may be made in materials and in structure andarrangement of parts, within the spirit of the invention and the scopeof the subjoined claims. What is claimed is: a LAn evacuated containercomprising a receptacle, an inner cover closing said receptacle, and anouter cover on said receptacle and enclosing said inner cover, a part ofsaid outer cover having spacer elements resting on the top of said innercover whereby portions of the outer cover are spaced from portions ofthe inner cover, said spacer elements being arranged incircumferentially spaced manner around a concentric opening formed insaid inner cover, said spacer elements thereby defining an outer chambersurrounding an inner valve chamber, said outer cover having openingscommunicating with the exterior atmosphere and with said outer chamberonly, said concentric opening communicating only with the interior ofsaid receptacle and with said valve chamber, and a valve in said valvechamber and normally closing said concentric opening,

2. A stopping device of the type including a. rigid cap adapted to besecured to the edge of the neck of a bottle which comprises, incombination, a rigid circular member fitting in said cap so as to becaught between the inner face of said cap and the edge of the bottleneck, both of said cap and said circular member being provided with atleast one hole, and a resilient element caught between said cap and saidcircular member so as normally to cover the hole provided in saidmember, said element being adapted to be deformed under the effect of apredetermined overpressure in said bottle, so as to con- 20 nect therespective holes of said cap and said member together.
